Microbiological synthesis optimization of probiotic microorganisms

The modern agro-industrial complex of the Russian Federation produces a significant number of by-products containing valuable nutrients. The article considers the possibilities of using secondary raw materials of agro-industrial sector in biotechnology industry. The role of waste processing of agricultural raw materials in optimization of lactobacilli cultivation process has been studied. Experimental studies of growth dynamics of probiotic microorganisms Lactobacillus plantarum on complex nutrient media using food and agriculture production waste were carried out. The optimal composition of the nutrient medium for lactobacilli growth and the time of microorganisms cultivation corresponding to the maximum increase of biomass were determined. Comparative analysis of media components for growing Lactobacillus plantarum according to the growth index of probiotic microorganisms was carried out. The growth stimulating role of such substrates for cultivation as beet pulp and corn gluten has been established
